yes, the two stackoverflow article show the correct way of doing it. Basically what you have to do it - get the XFA (as you already do) - do the manipulation (as you already do) - create a new COSStream or PDStream serializing your XML into it ( which you don't seem to be doing) - create a new PDXFA from that ( which you don't seem to be doing) - set the new PDXFA to be used by the AcroForm.
